The Antec case has a big knob (rotary encoder), and a VFD. Both are USB connected, so I wrote a little standalone utility to query MySQL and Myth for the recording status and it displays that as scrolling text on the top line of the VFD. The bottom line shows time, date, and CPU temperature.
The large knob is used to pause / manually scroll the display (no other good use for it). Infrared remote control of the entire setup is provided by the Hauppauge and Logitech remote controls that were included with the hardware.
There's also a wireless keyboard & mouse combo stored to the left of the cabinet.
